Normally you should be able to just put in the CD and then reboot the computer and the installation will start.

If it won't boot on the CD, you can make a bootfloppy with CDROM support (rescuedisk) this way:
Go into safe mode, click start | settings | control panel | add/remove programs | windows installation.
Here there should be a button that will create a bootdisk.
Use this to boot the machine, and when you get the a:\> prompt, THEN type e:\setup or e:\install. I never can remember which one it is. :)

I don't think you can do it from safe mode, and you can't do it from Command prompt only because of lack of cdrom support.
Sounds like a reinstall of Win98 over top of itself is in order.

You could try booting up into Safe mode and run SFC (System File Checker) and see if it finds and replaces any corputed files.

never attempted a reinstall of win98.  how do you boot in safe mode (thought that was only NT)?
Free Tool: ZipGrep

ZipGrep is a utility that can list and search zip (.war, .ear, .jar, etc) archives for text patterns, without the need to extract the archive's contents.

One of a set of tools we're offering as a way to say thank you for being a part of the community.

On most machines you can get the boot menu by tapping the F8 key as the computer is first booting up, on a few you may need to do the same with the Ctrl key.
Do you have a Win98 disk or only a recovery disk?
Rayt333 is correct, Hit F8 when "Starting Windows 98" appears and you will get a boot menu, where you can choose safe mode..

My advice to you, is this:
Hit F8 when "Starting Windows 98" appears and you will get a boot menu. In here choose "Dos prompt only".
Type this command and hit Enter:

In the program choose a date prior, as to when this started happening, and Windows will replace the registry with a version of that date. When finished, reboot and see if the problem has gone.

Hope this helps
I agree with tonnybrandt if it's been less than 5 days. You might have to type:

Then type scanreg/restore.

Or if you get into safe mode, got o Start>Run, type msconfig, click the startup tab and uncheck machne Debug Manager.

Or Hit F8 on startup, and choose Command Prompt. Type edit c:\windows\system.ini Under
[boot] Change

If Program manager loads go to File>Run, type msconfig, go to the Startup tab and uncheck everything.

Either go back and change system.ini to the original or if you're comfortable using File manager, you can type Winfile under the File>Run and check your configuration files.
To open autoexec.bat, you go to the root of C: drive, highlight it, choose Run from the file menu and type notepad autoexec.bat

Hopefully this will get you back in.

What hardware changes have you made? '>)...T

A repair of Internet Explorer may solve this.

In AddRemove Programs in Control Panel choose Microsoft Internet Explorer xxx, click remove then choose repair.

This behavior can occur if the Microsoft Windows 95 version of the Explorer.exe file is located in the root folder of drive C.



In Windows 98, boot the computer to Safe Mode Command Prompt.

Type the following at the prompt: ren c:\explorer.exe explorer.old

Press ENTER.

I've tried all of the above but with no luck!
Even reinstalling Win98 ???
dooner1Author Commented:
I was hoping to avoid reinstalling.  It seems as though if it's only Explorer that's corrupt, reinstalling is a bit drastic.  I'm trying to help a friend resolve this remotely, and I don't have access to the machine, so for her to reinstall might be too much.  I'll have her take it to a local tech place -- thanks for all your help anyway.
reinstalling over top of itself is not hard to do and will not cause you to lose any installed programs.
This takes about an hour to do, how much time have you already wasted?   What do you think the computer store is going to do?
dooner1Author Commented:
true, but I'm not sure I can walk her through it remotely.  If the machine won't boot at all, or using safe mode only, does it recognize the hard drive?
Yes it does, otherwise it wouldn't start at all, and a reinstall over the previous installation is not hard to do at all. The only time that you need to do anything is when it come and ask you where to install. It will default to something like C:\windows.001 and this has to be changed to c:\windows.

One other thing that can be a problem, is if you have an oem version of the windows 98 cd. Some of these will not install if an OS is installed already on the HD. If this happens follow these steps to bypass the detection:
When "starting windows 98" appears when starting the computer, hit F8 and choose "Command Prompt only".
rename c:\windows\ c:\windows\win.bak
and hit Enter.
Now reboot and the installation process will not detect the installed windows 98.

so we restart the machine in safe mode, insert the win98 CD snd type something like e:\setup.exe ?
dooner1Author Commented:
I'll accept this as the answer.

Rayt333: could you have a look here:

dooner1: Glad you got your problem solved.
